Here are solutions and answers for these problems
The answer to the question can be found by setting up a proportion such as 7/14.4=x/24.6 which gives you 11.9583 ft
The correct answer is A.
You have direct variation if x and y are modeled by the equation

In this case, m is the constant of proportionality. So, if the constant has to be 2, the equation becomes

A side note: Actually, option C has a constant of proportionality of two as well, except the roles of x and y are interchanged. I chose option A because usually you want the y = mx form, but the names of the variables are obviously meaningless.
Answer: A. 14
Step-by-step explanation:
If e=9 and c=5 you would replace e+c with those
9+5=14
Answer:
56 units
Step-by-step explanation:
add all numbers then divide by 5
30+45+50+75+80 = 280
280/5 = 56
